90 - 110°C / 194 - 230°F.

Short Circuit Protection

Activated when DC rail is short-circuited.

Surge & Inrush Protection

Sustain 2kV surge stroke.

"This PSU features PowerGuard & Advanced Protection Guard function to monitor the PSU itself. With tri-color LED, PowerGuard tells you the current PSU status. In case of abnormal situations, the power supply will automatically turn off to aviod potential danger to itself and other system components."

OFF

OFF

No AC Input – Turn the I/O switch to the ON position.

OFF

ON

No AC Input or PSU malfunction – Check if AC cable is firmly plugged into wall outlet and AC inlet. If LED still does not turn to orange light, then contact SAPPHIRE service center.

Orange

ON

PSU normal and system in standby/sleep mode.

Green

ON

PSU normal and system operational.

Red

ON

System abnormal, protection circuit activated.

If you push the system power button, and PSU refuse to turn on, the LED turn from orange to red light:

-Short Circuit protection activated.

-Completely check if all connectors are correctly inserted, and clean the chassis to prevent undesired objects, which might short circuit any device/terminal.

If during system operation, the PSU suddenly shut down:

-Touch the PSU housing and check if it is hot. If yes, wait till cool down and restart the system to see if all system fans and PSU fan are running. Add or replace the system fan if required.

-If same situation repeat, recheck if all connectors are well connected to system, or redistribute certain drives/PCI-E power to different 12V rail connector.
